Re: In need of some advice, if i'm too jealous or what.
Unfortunately, you can't tell if they had video-sex (or cyber sex).
But what you can do is install a recorder on your computer to monitor the activity during the time she's using the computer when you're not around.
Does she work or is she a stay-at-home mom?
Are you providing her with emotional/physical needs?
Davelli0331: If a GNO, or alcohol, or an attractive coworker, or a past flame on FB were all that were needed for someone to cheat, then I think that person had that defect in their integrity all along. All they ever lacked was the opportunity to act on their lack of integrity and the circumstances required to rationalize it to themselves.
